﻿NORTH AMERICAN FAUNA. 



[Xo. 12. 



but ill tlie uucertainty Fitymys slioukl be retained as the one adopted 

 by all subsequent Avriters. o 



Cunicuh(s TTagler, 1S30 (Xat. Syst. d. Ampliibien, p. ^1), included 

 three species [C. lemmus, C. torquatiis, and C. aspalax) now referred to 

 three genera and two subfamilies. The name has been commonly 

 applied to toniimtus and its congeners, but its use is invalidated by 

 Cuniculus Brisson, published fifty-eight years before. 



Hemiotomys DeSelj'S-Longchamps, 1836 (Essai monograph, sur les 

 Campagnols des environs de Liege, p. 7), was proposed as a section of 

 ArricoJa i=2Iicrotiis) to include the species fidrus { = arvaUs) and 

 anqyJiibius {=tery€str>s). As each of these had already received a ten- 

 able subgeneric name, Hemiotomys lapses into synonymy. 



Pinemys Lesson, 183G (Hist. Xat. d. Mamm. et Ois. decouv. depuis 

 1788, Compl. (Euvres de Buffon, Y. p. 13G), based on JPsammomys pine- 

 torinn LeConte, is a synonym of Fitymys McMurtrie. 



Lagurus Gloger, 1811 (Gemeinniitz. Hand- u. Hilfsbuch d. ZS^aturge- 

 schichte, I, pp. XXXI, 97), is the earliest available name for the sub- 

 gentis of which 2Ius lagurus Pallas is the type.^ (See footnote, p. 19.) 



Dicrostonyx Gloger, 1811 (1. c, pp. XXXI, 97), is the tenable name 

 for the genus usually known as Cuniculus ^2iglQ\\^ This name has 

 escaped notice until very recently.^ 



Xeodon Hodgson, 1819 (Ann. & Mag. Xat. Hist., 2d ser.. Ill, p. 203), 

 is a synonym of 21icrotus, as its type, 3'. siltlximensis Hodgson, can not 

 be sei)arated subgenerically from Jlicrotus arralis. 



'• 2IyoJemmus Pomel. 1851 (Ann. Sci. Soc. Aiivergne),'' is a synonym 

 of Dicrostonyx Gloger. This statement is made on the authority of 

 Trouessart (Cat. Mamm. viv. et foss., Eodentia, Ft. II, p. 15G, 1881). as 

 I have had no opportunity to verify the reference. 



Misothermus Hensel, 1855 (Zeitschr. der Deutsch. geolog. Gesellsch., 

 YII, p. 192), is stated by the author to be based on jlyodes torqnatus 

 Pall. It is thus antedated by Jlyolemmus Pomel and Dicrostonyx 

 Gloger. 



Fedomys, CMlotus, and Synaptomys are three names proposed by 

 Baird in 1857 (Mamm. X. Am., pp. 516, 517, 558). All are tenable for 

 the groups to which they were applied. Fedomys and Chilotus iire sub- 

 genera of Microtus. Their tj^x^es are Microtus austerus and 21. oregonus^ 

 respectively. Synaptomys is a genus, with S. cooperi as the tyyie. 



^Gloger's description is as follows: Tlieils auf dem Ural uud anderen Gebirgen, 

 theils aiicli in tieferen Gegenden Sibiriens, giebt es^ drei oder vier andere Arten mit 

 kleinen, rundlichen oder spitzigen Danmuageln uud von einfaclierer Fiirbung 

 (Lagurus), die zum Theile niclit Tveniger zum AVauderu geneigt scheinen. Z. B. L. 

 mignitorius.'' 



-Gloger says: "Von den nordamerikaniselieu Lemmiugen zeielinen sich manehe 

 durch ein Paar hochst sonderbare (gleichsam doppelte) Vorderkrallen aus, die 2 oder 

 gar 3 Spitzen iiber eiuander zu liaben sclieinen, weil sie nnter den Niigeln grosse, i 

 harte Ballenliervorragungen besitzen. Sie konnen daber Gabelkraller (Dicrostonyx) | 

 beissen."' j
